Pi2Carplay v0.2.0

v0.2.0

Bluetooth calling, vehicle microphone support and live video controls for the Raspberry Pi 5 Android 16 image.

Boot-image correction: the original v0.2.0 download omitted the extended-partition tables, preventing Android from locating system/vendor. Download the replacement ending in -bootfix.img.gz. It restores the complete partition chain; all filesystem and program bytes are unchanged. Structural checks and archive verification pass; a fresh hardware boot of the replacement still needs testing.

Changes since v0.1.0

• Added Bluetooth hands-free calls through the paired phone, with two-way audio over CarPlay. Supports mSBC wideband speech with CVSD fallback, and routes the vehicle microphone into Android recording apps.
• Added an adapted AOSP Phone app with contacts, call history, dialpad and call controls. Hands-free Bluetooth identification enables iPhone Sync Contacts; the phone owner must approve sharing. Phonebook reconnects when permitted.
• Added a floating ongoing-call bar with contact name or number, timer, mute and hang-up controls. Tap it to return to Phone.
• Updated Phone with dark surfaces, rounded controls, a compact landscape dialpad and a rounded-square icon sized consistently in Home and Apps.
• Improved call-audio pacing and buffering, removed a duplicate playback route that caused discontinuities, and corrected microphone conversion and stream lifecycle handling.
• Fixed picture-in-picture clearance and keyboard layout around the persistent 104-pixel sidebar. Retained native Android Recents and split screen; deployment checks now verify the navigation service as well as Home's local sidebar.
• Added live 4/8 Mbps and 30/60 FPS controls to Home settings. FPS controls both Android rendering and capture/encoding, within the receiver's negotiated limit. Changes require no reboot. Clean images default to 4 Mbps / 30 FPS.
• Cached video-conversion shader locations. FPS changes send fresh H.264 configuration and a keyframe while retaining the USB session, negotiated geometry and audio.
• Polished Home settings with rounded glass surfaces and clearer controls, including scrolling on smaller displays.
• Added concise Google custom-ROM registration and stale compliance-cache recovery instructions in the main README. Each owner registers their own device; registration does not confer official hardware certification.

Clean-image setup

The image uses fresh userdata built from a program-only allowlist. It includes no personal accounts, saved Wi-Fi networks, Bluetooth pairings, contacts, call history, browser/app data, device identifiers, authorized ADB hosts, test logs or private signing keys. Configure your own Wi-Fi, Google account and phone pairing after flashing. ADB requires host authorization.

First setup enables dashboard navigation and Phone's floating-call permission. Subsequent boots retain the owner's choices. Existing test-device data and the previous release are retained separately.

Validation and remaining tests

On-device checks verified all four video combinations within one capture process, Android's actual 30/60 FPS scheduling, GPU conversion, H.264 configuration/keyframe transitions and synthetic audio clocks. The persistent sidebar, Recents and two-app split screen were checked; navigation remained enabled after restart. Earlier vehicle trials confirmed normal microphone quality and Android app microphone access.

The user reported that the latest combined build passed the car test. A fresh-image first boot on hardware remains untested. No performance claim is made for sustained 60 FPS at every resolution. Broader vehicle compatibility and occasional restart/power-on behavior remain unqualified.

Image assembly, the exact userdata allowlist, the privacy audit and full archive decompression checks passed. See the accompanying image manifest, privacy audit, source checks and SHA256SUMS.

Packaging fix and regression test.

Pi2Carplay v0.1.0

Initial Pi2Carplay release for community testing. More vehicles and display sizes need testing.

Flash Pi2Carplay-v0.1.0.img.gz with Raspberry Pi Imager. Use a fast 16GB-or-larger microSD and follow the README for first boot.

The adaptive runtime passed vehicle testing, including negotiation of the usable display area. GPU conversion, live capture, encoder and audio startup checks pass. The image uses fresh program-only userdata with no personal accounts, passwords, saved networks or authorized ADB hosts. Full archive, partition and userdata verification passed.

All source code, including the complete patched kernel and build inputs, is on main under src/kernel. Component licenses, including the Android base's non-commercial terms, remain applicable; see LICENSE-SCOPE.md.

Verification records and the image checksum are in docs/releases/v0.1.0 on main.
